THRESHING-MACHINE. y

Specification of Letters Patent.

Application filed May 29, 1906. Serial No. 319,316.

To all whom it may concern.

Be it known that I, JOHN SANDERS, a citizen of the United States, residing at Dundee, in the county of Archer and State of Texas, have invented a new and useful Threshin Machine, of which the following is a speciiication.

This invention relates more particularly to that class of threshing machines, in which fan mechanism is employed for threshing out the grain from the straw.

The rincipal object is to provide an exceeding y simple structure, which is very rapid and effective in operation, is light in weight, eliminates the necessity of the usual cylinder and beater, and reduces the friction on the bearings and the amount of power necessary to drive the machine.

An embodiment of the invention is illustrated in the accompanying drawings, wherem:-

Figure 1 is a side elevation of a portion of a separator, showing the improved threshing mechanism applied thereto. Fig. 2 is an end elevation of the same, portions being shown in section. Fig. 3 is a vertical sectional View on the line 33 of Fig. 2. Fig. 4 is a side elevation of the threshing cylinder. Fig. 5 is a sectional view on the line 55 of Fig. 2. Fig. 6 is a cross sectional view on the line 66 of Fig. 1.

Similar reference numerals designate corresponding parts in all the figures of the drawlngs.

The separating mechanism may be of any well known character, the present improvement relating more particularly to the threshing mechanism and the feeding means therefor. This mechanism and feeding means may be applied to practically any of the well known separators, if desired. In order to fully show the application of the invention, a portion of a separator is illustrated, comprising a suitable frame or body 7, within which the se arating mechanism is located, a ortion of said mechanism being illustrate in Fig. 5, wherein the lower end of a straw carrier 8 is shown with a grain pan 9 located therebeneath.

Mounted on one end of the frame or body 7 are spaced fan casings lO and 11. casing 11 constitutes part of the threshing mechanism, and has a discharge throat 12 for directing the material rearwardly into the separating means. Said casing also has a peripheral inlet 13. The other casing has a The fan' central inlet opening 14 in its outer side, and a peri heral outlet 15. This outlet 15 is connecte to the inlet 13 of the casing 11 by an upwardly arched spout or conveyer tube 16 that bridges the space between the casings, and is disposed transversely of the machine. A downwardly inclined grain-directing chute 17 communicates at its lower end with the inlet 14 of the casing 10. This chute receives the material from a band cutter and feeder (not shown), which may be of any suitable construction.

A shaft 18 extends across the space between the fan casings 10 and 11, and projects into said casings, said shaft being journaled in suitable bearings 19. The ends of the shaft, located within the casings, carry fans 20 and 21. the shaft between the casings, is driven from any suitable source of power by a belt 23 passing about said pulley, and thus constitutes driving means for the shaft and fans.

The separating mechanism may, if desired, be operated from another'pulley 23*, also mounted on the shaft between the casings.

The casing 11, as already stated, consti tutes a part. of the threshing mechanism. Within it is located a concave 24, having transverse ribs 25, secured in position by bolts 26. Access to the interior of the casing may be readily gained through an opening 27, formed in the outer side of said casing, and normally closed by a suitable door 28.

In operation, the grain to be threshed is directed by the chute 17 into the casing 10, where it is rapidly revolved by and delivered with the blast of air from the fan through the spout or conduit 16 into the threshing mechanism, the fan 20 thus constituting in effect, feeding mechanism for the latter. In this second casing, a further rapid rotation is given the straw and grain, which passes over the concave, so that the grain is thoroughly threshed out of the heads. From the threshing mechanism, the fan delivers the material into the separating mechanism.

Experience has demonstrated that this mechanism is highly effective for detaching the grain from the straw, and is moreover extremely rapid in operation. It is also very light in weight, and eliminates the necessity of the toothed cylinders and beaters. Moreover, with this structure, there is no dust at the front of the separator, the dust being carried ofi with the blast of air and delivered from the rear end of the separator, leaving Patented May 5, 1908.

A pulley 22, mounted on condition. By havtion between the fans is greatly reduced, and i oly less power is neces- 'tfing the machine than is required e employing the ordinary toothed s and concaves l/ 1cm the foregoing, it is thought that the ,;I1StIL1Cl3iOI1, operation, and many advan- 4 tages of the herein described invention, will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is:-
